Microfibers from clothes washing machine: A hidden plastic source

The hidden cost of every laundry cycle

Your clothes are shedding plastic into the water supply every single time you run a cycle. A 2026 study published in ACS Environ Au confirms that frictional abrasion between synthetic fabrics is the primary driver of this release. When polyester fabrics rub against each other during a wash, they break down into microplastic fibers that eventually end up in our waterways.

Friction is the enemy

Researchers found that low-friction coatings, specifically polydimethylsiloxane (PDMS), can significantly curb this pollution. In laboratory simulations, using these finishes reduced fiber release by up to 42% for coated fabrics. Even more telling, the presence of a finished fabric in the wash reduced the shedding of uncoated fabrics by up to 28%. The total reduction in microplastic output reached as high as 37% depending on how the fabrics were oriented.

What you can do

You cannot change the chemistry of the clothes you already own overnight, but you can change your habits. Start by washing synthetic loads on shorter, gentler cycles with cold water to reduce mechanical stress. When it is time to replace your essentials, look for natural fibers like organic cotton, wool, or linen that do not shed plastic. We have curated a selection of non-toxic home alternatives to help you transition away from synthetic materials that contribute to this cycle of pollution.
